This paper consists of a series of reflections of external sensitive knowledge: what does it mean to know a color, a sound, etc. Three different views are compared Zubiri, Leonardo Polo and Aquinas.

Background: COVID-19 has taken many lives worldwide and due to this, millions of persons are in grief. When the grief process lasts longer than 6 months, the person is in risk of developing Complicated Grief Disorder. The CGD is related to serious health consequences. To reduce the probability of developing CGD a preventive intervention could be applied. In developing countries like Mexico, the psychological services are scarce, self-applied interventions could provide support to solve this problem and reduce the health impact (...) even after the pandemic has already finished.Aims: To design and implement a self-applied intervention composed of 12 modules focused on the decrease of the risk of developing CGD, and increasing the life quality, and as a secondary objective to reduce the symptomatology of anxiety, depression, and increase of sleep quality. The Intervention Duelo COVID follows the principles of User Experience and is designed according to the needs and desires of a sample of the objective participants, to increase the adherence to the self-applied intervention, considered one of the main weaknesses of online interventions.Methods: A Randomized Controlled Trial will be conducted from the 22nd of December of 2020 to the first of June 2021. The participants will be assigned to an intervention with elements of Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, Mindfulness and Positive Psychology. The control group will be a wait-list condition, that will receive the intervention 1.5–2 months after the pre-measurement were taken. The Power Size Calculation conducted through G*Power indicated the need for a total of 42 participants, which will be divided by 21 participants in each group. The platform will be delivered through responsive design assuring with this that the intervention will adapt to the screen size of cellphones, tablets, and computers.Ethics and Dissemination: The study counts with the approval of the Research Ethics Committee of the Autonomous University of Ciudad Juárez, México, and it is registered in Clinical Trials. The article is sent and registered in clinical trials before the recruitment started. The results will be reported in future conferences, scientific publications, and media. (shrink)

This study aimed to investigate the student-athletes' capability to face the academic, sport, and social challenges during the coronavirus disease 2019 (COVID-19) lockdown and to disclose novel aspects of dual careers. A 32-item online survey encompassing demographic characteristics, sport and university engagement, support and dual-career benefits, physical activity, sitting time, and the time deemed necessary to recover the previous level of performance was developed. Four hundred sixty-seven student-athletes (males: 57%, females: 43%) from 11 countries, competing in 49 different sports (individual: (...) 63.4%, team: 36.6%) at regional (17.5%), national (43.3%), and international (39.2%) levels, and enrolled at high school (21.9%) and university (78.1%) levels completed the survey. During the lockdown, the respondents decreased the time dedicated to sport and academics, although they maintained an active lifestyle. Student-athletes from countries under severe contagion were more likely to train at home, dedicate to academics, and receive support from the coach but less likely receive support from their teachers. With respect to their team sport counterparts, athletes competing in individual sports trained more and were more likely to receive support from their coaches. International athletes showed the highest training time and support from their coaches and as student-athletes. High school students received more support from their coaches and teachers, whereas university students were more likely considering dual careers useful to cope with the COVID-19 pandemic. This study substantiates the relevant role of competitive sports participation in the maintenance of active lifestyles, with student-athletes considering home training and e-learning valuable resources during the lockdown. Furthermore, their sport and academic commitments helped student-athletes cope with the emergency of the COVID-19 pandemic. (shrink)

Résumé : Les domaines de la philosophie et de la théorie politique ont connu un certain nombre de changements au cours des quarante dernières années. L'un attire notre attention tout particulièrement ; le basculement d'un point de vue national, cristallisé par le contrat social rawlsien, vers un point de vue non-national. En effet, plusieurs penseurs abordent un ensemble de phénomènes considérés comme nouveaux, tels que les traités de libre commerce et l'économie globale, les entreprises et les institutions supra et transnationales, (...) l'immigration et les contrôles frontaliers etc. Ces changements sont intéressants puisqu'ils obéissent, principalement, à une évolution majeure du terrain politique et social que l'on appelle mondialisation. Les théoriciens travaillant dans le domaine de la justice globale semblent s'adresser à deux questions différentes mais reliées. La première concerne la justice globale : dans quelle mesure et pourquoi l'ordre mondial est-il juste ou injuste ? Qu'est-ce qu'un ordre global juste ? La deuxième est dans un sens corollaire à la première, et concerne la responsabilité : qui devrait être blâmé ou digne d'éloge pour l'ordre mondial ? Est-ce que les citoyens sont responsables de l'ordre mondial ? Qui devrait redresser ses éventuelles conséquences injustes ? Face à l'économie mondialisée et aux institutions politiques et économiques internationales et trans-nationales, cette interrogation devient légitime et nécessaire : suis-je responsable à l'égard des travailleurs des sweat shop lorsque j'achète des habits à Auchan ou bien à l'égard des caféiculteurs très mal payés lorsque je prends un capuccino dans un café Starbucks ? Est-ce que les citoyens sont responsables des traités de libre commerce que leurs gouvernements signent ? Ces questions sur la responsabilité des individus dans le contexte de la mondialisation seront l'enjeu de ce travail de recherche. Nous interrogerons plus exactement la responsabilité d'un agent lorsqu'il fait partie d'un chaîne causale complexe, lorsqu'il participe d'une injustice structurelle. Ainsi, il ne s'agit pas seulement d'une chaîne causale, mais de connexions qui sont l'issue d'un changement des modes de productions, de consommation et de la concurrence dans un marché mondialisé. Plus important encore, il ne s'agit pas simplement de la responsabilité individuelle mais plutôt de la responsabilité individuelle en tant que citoyen, et donc d'une responsabilité politique. Elle peut certes être individuelle, mais nous devons tenir compte du fait qu'elle doit être pensée en tant que responsabilité politique, et pas uniquement morale, puisque l'individu et ses actions sont déterminés par des communautés politiques dans lesquelles il participe, ou dans lesquelles il est représenté. Ainsi, la mondialisation nous invite à repenser la responsabilité individuelle pour pouvoir rendre compte des intuitions morales et politiques qui guident une bonne partie du champ de la justice globale. Pour cela, nous verrons dans un premier temps la manière dont les théories de la justice globale essaient de répondre à ce défit. Grâce à cela nous dégagerons l'hypothèse qui nous guidera, l'idée que dans la mondialisation, un agent peut être responsable, avec d'autres, des raisons pour lesquelles il n'est pas considéré comme responsable. C'est-à-dire qu'il sera méta-responsable. Dans un second temps, nous essaierons de déterminer un model de responsabilité individuelle, et de comprendre comment la responsabilité est attribuée. Ensuite, nous essaierons de formuler une manière de concevoir la responsabilité politique. Grâce à ces deux éléments, la responsabilité individuelle et la responsabilité politique, nous pourrons parvenir à formuler une conception de la méta-responsabilité comme forme de penser l'agentivité traversée par la mondialisation.

The current times call for reforms in educational processes. The Covid-19 pandemic had an unforeseen impact on the educational system in all countries. This need for change requires new pedagogies and new methods for teaching and learning. Understanding the need for change is essential for the formulation of adaptive proposals, as well as for the generation of training activities to complement the teaching curriculum. New educational practices lead to a vision of educational quality, with new approaches that allow the continuous (...) integration of knowledge and permanent interaction with the student. This paper presents an analysis of the new teaching methodologies in times of confinement due to the pandemic caused by Covid-19. Keywords: Teaching methodologies, educational system, learning process. References [1]É. Tremblay-Wragg, C. Raby, L. Ménard y I.

Argumentation is the gear of a cognitive process of reconstruction when it manifests itself in the discursive proximal space. The cognitive-semiotic perspective of multimodal argumentation suggests that, depending on the knowledge, the codes and signs employed (modes) and the context, certain multimodal structures can lead some audiences towards an accurate mental representation of argumentation, without the need forany formal standardized and verbal structure. We are able to argue with other(s) effectively without the need for a verbal translation of the contents (...) in a space that includes the semiotic interpretation of the message. (shrink)

By weakening an inference rule satisfied by logic daC, we define a new paraconsistent logic, which is weaker than logic \ and G′ 3, enjoys properties presented in daC like the substitution theorem, and possesses a strong negation which makes it suitable to express intutionism. Besides, daC ' helps to understand the relationships among other logics, in particular daC, \ and PH1.

El objetivo de este artículo es definir la concepción del acto involuntario de Francisco Suárez y mostrarla como un medio que permite comprender y profundizar en su teoría de la acción humana. En esta cuestión, el Doctor Eximio parte de presupuestos elaborados por Tomás de Aquino que amplía y adapta siguiendo sus propias tesis metafísicas y teológicas sobre la relación entre Dios y las creaturas. Mostraremos cómo Suárez vincula el verdadero involuntario con el _simpliciter_, lo forzado, necesario e indeseado, dejando (...) al _secundum quid_ como un acto mixto en el que la libertad y la voluntad, pese a las injerencias externas, no quedan anuladas. Por último, subrayaremos las consecuencias de la definición suareciana de lo involuntario sobre la noción de libertad, haciendo patente que tanto una como otra serían imposibles fuera del marco teórico que él sustenta, caracterizado por la eficiencia humana (y su dependencia de la divinidad) y no por la premoción física.

This is a Political Economy study on migrants-citizens relations management in the United States of America, with special attention to the religious factor and the pendulum effect. There is a model switch, from integration policies to official persecution, under a high social opportunity cost. Also, there is a split between the State and civil society, causing civil disobedience and sanctuary network across the country. The paper focuses on the development of the Sanctuary Movement, as a case of popular action against (...) to the power elite policies and their sanctions. There was a revival of this movement during the values crisis or 2008 recession, but at the same time there was a critical division into the movement, with higher tension for the migrants. (shrink)

According to the broaden-and-build theory of positive emotions, the frequency of positive emotions is associated with the development of positive attitudes, cognitions, and behaviors in organizational contexts. However, positive and negative attitudes at work might also be influenced by different personal and job resources. While emotional intelligence has been significantly associated with positive job attitudes and personal well-being, no studies have yet examined the joint role of teacher happiness and emotional intelligence in key teacher job attitudes. The present study assesses (...) whether emotional intelligence interacts with levels of teacher happiness to jointly explain important teacher job attitudes. A total sample of 685 teaching professionals filled out a battery of scales including subjective happiness, emotional intelligence, job satisfaction, and turnover intention. Our results revealed that subjective happiness was significantly associated with both higher job satisfaction and lower turnover intention. Likewise, emotional intelligence was positively related to happiness and job satisfaction, and negatively related to turnover intention. Finally, interaction analysis showed the main effects of happiness and emotional intelligence in explaining teacher job attitudes. Beyond the main effects, the interaction effects of happiness and emotional intelligence were significant in predicting all teachers' job attitude indicators, even controlling for the effects of their sociodemographic variables. This work expands our knowledge about the role of teachers' positive emotions in the development of positive work attitudes, and also supports the inclusion of emotional skills in future teacher preparation programs as resources to facilitate work-related well-being.

The fundamental principles of the classical utilitarian school characterize this trend as an administrative and legal criminology. This had two implications. On the one hand, the motives, and ultimate causes of the behavior and the unequal consequences of an arbitrary rule were ignored. On the other hand, the role of the judge was reduced to enforcing the law, while it was up to the judge to set a penalty for each offence. At the end of the nineteenth century, these principles (...) saw the gradual emergence of another punitive episteme that had emerged as a result of the colonization of the legal space by the positive sciences and etiological action programs. This was not a planned and pre-established course, but the confluence of a series of theories and programs for penal prevention that Michel Foucault summarized as the realization that the law was increasingly functioning as a norm. Now, criminality, besides being the object of scientific interest, also constitutes the indicator of a social problem and therefore its insertion in an economy of changing power. (shrink)

In this paper we present a semantic analysis of the application of didactic constructivism to chemical education. We show that the psychological basis of constructivism yield, when applied to chemistry, an internalist semantics for the chemical names. Since these names have been presented as typical examples of an externalism for kind terms, a fundamental incompatibility ensues. We study this situation, to conclude that it affects chemical education at every level. Finally, we present a preliminary analysis of this problem from the (...) point of view of physics. (shrink)

Studies of individuals under conditions of confinement or severe social and physical restrictions have consistently shown deleterious mental health effects but also high levels of adaptability when dealing with such conditions. Considering the role of physical activity and sport in psychological adaptation, this paper describes a longitudinal study to explore to what extent the imposed restrictions due to the outbreak of SARS-CoV-2 may have affected athletes’ mental health outcomes and how far the process of adaptation to confinement conditions is differentially (...) affected depending on whether the sports activity was practiced individually or in a group, and outdoors, indoors, or both. Two hundred and seventy-four athletes were assessed over 7 weeks using the GHQ-28 and an ad hoc survey exploring the practice of physical activity. A mixed-model fixed effects ANCOVA was used to analyze the effects of time, place, and company in which the sport was practiced, with an index of the amount of physical activity expended as a covariate. Results show a significant effect of time in three out of four of the GHQ-28 subscales, in all cases showing a consistent adaptation to conditions over time. Results also show that playing sport indoors, outdoors, or both, and practicing alone vs. with others differentially affect the somatic symptoms exhibited during confinement: Athletes who practiced sport with others showed higher levels of somatic symptoms at the beginning of the set of data but a quicker rate of adaptation. Differences arising from practicing sport alone or with others were more pronounced in the case of indoor sports, which could be related to the fact that physical activity that can be practiced during confinement is more similar to that practiced indoors alone. Implications relating to what sport psychologists and other health professionals may offer to athletes in stressful situations are discussed. (shrink)

This paper investigates the effects of relative position and proxemics in the engagement process involved in Human-Robot collaboration. We evaluate the differences between two experimental placement conditions for an autonomous robot in a collaborative task with a user across two different types of robot behaviours. The study evaluated placement and behaviour types around a touch table with 80 participants by measuring gaze, smiling behaviour, distance from the task, and finally electrodermal activity. Results suggest an overall user preference and higher engagement (...) rates with the helpful robot in the frontal position. We discuss how behaviours and position of the robot relative to a user may affect user engagement and collaboration, in particular when the robot aims to provide help via socio-emotional bonding.

Este ensayo da cuenta de la presencia del fenómeno camp como manifestación estética en el poema Strip Tease del escritor argentino Néstor Perlongher. Dicha manifestación estética aparece como un contradiscurso frente a los discursos de lo normativo y de lo permitido para dar cuenta de una manera de ser y de sentir mediante la escritura. Para el análisis del poema se partió de la relación que se puede establecer entre signos semióticos y a partir de los cuales una sintagmática actualiza (...) relaciones paradigmáticas. La razón de este análisis consiste en poder demostrar cómo se manifiestan las ideologías y en este caso, específicamente, la visión del mundo del amplio abanico de posibilidades genéricas que se han exteriorizado con la escritura, frente al denominado discurso gender.

Code-based cryptography is currently the second most promising post-quantum mathematical tool for quantum-resistant algorithms. Since in 2022 the first post-quantum standard Key Encapsulation Mechanism, Kyber (a latticed-based algorithm), was selected to be established as standard, and after that the National Institute of Standards and Technology post-quantum standardization call focused in code-based cryptosystems. Three of the four candidates that remain in the fourth round are code-based algorithms. In fact, the only non-code-based algorithm (SIKE) is now considered vulnerable. Due to this landscape, (...) it is crucial to update previous results about these algorithms and their functioning. The Fujisaki-Okamoto transformation is a key part of the study of post-quantum algorithms and in this work we focus our analysis on Classic McEliece, BIKE and HQC proposals, and how they apply this transformation to obtain IND-CCA semantic security. Since after security the most important parameter in the evaluation of the algorithms is performance, we have compared the performance of the code-based algorithms of the NIST call considering the same architecture for all of them.

The high levels of land use, inputs, and investment, along with the specific forms of organization and management that characterized Cuba's state extensive growth model during the 1980s, could not overcome the challenges posed by the integrated care required by the sugarcane crop and corresponding industrial activities. Starting in 1993, large state farms have been converted into Basic Units of Cooperative Production with some degree of autonomy. Although first-year production results are not satisfactory, it is too early to evaluate their (...) performance. Their establishment, however, is a step in the right direction to alleviate the problems that the previous forms of organization and management inherent to the state extensive growth model were unable to solve.
